Description

Technical Field

[0001] This utility model belongs to the technical field of radiator processing equipment, specifically relating to a high-precision drilling device for radiator fin processing. Background Technology

[0002] As a key thermal management component in electronic devices, heat sinks typically require multiple mounting holes on their substrates for fixed connection with heat dissipation pipes or heat-generating elements. In the prior art, drilling holes in heat sink fins is mostly done using ordinary bench drills or single-axis CNC drilling machines.

[0003] In actual production, when multiple holes need to be machined on the radiator substrate, if a single-head drilling machine is used, each hole needs to be machined one by one. The multiple movements of the worktable or spindle will introduce cumulative positioning errors, resulting in hole spacing deviations, which makes it difficult to meet high-precision installation requirements. If a traditional multi-spindle drilling machine is used, the spacing between its multiple spindles is usually fixed, which cannot flexibly adapt to the changing hole spacing requirements of different radiator models, resulting in low versatility. Radiator fins are usually thin-walled parts made of aluminum or copper, which have poor rigidity. Traditional clamping fixtures are prone to bending and deformation of thin-walled substrates due to uneven force application, and the poor fixing effect during drilling may also cause the radiator fins to vibrate, affecting drilling accuracy, which is not convenient for high-precision and efficient processing of radiator fins. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a high-precision drilling device for radiator fin processing. This high-precision drilling device can cover the processing of radiator fins with different hole spacing requirements, fundamentally eliminate the cumulative error caused by multiple movements of the worktable, ensure extremely high hole spacing consistency accuracy, process multiple holes at once, greatly improve drilling efficiency, effectively suppress the vibration and bending deformation of thin-walled radiator fins during the drilling process, and ensure drilling quality.

[0006] Preferably, the adsorption base mechanism includes a grid base with a negative pressure chamber, a negative pressure groove, and adsorption holes. The grid base is fixedly connected to the upper surface of the base, and the negative pressure groove is opened in the middle of its upper surface.

A negative pressure pipe connected to the negative pressure chamber is fixedly connected to the middle of the side of the grid base.

[0007] Preferably, the clamping mechanism includes a sliding block, a compression spring, and a clamping plate. The clamping plate is vertically fixed to the lower surface of the sliding block, and the sliding block is laterally slidably connected to the inside of the sliding frame. The compression spring is horizontally fixed to the side of the sliding block away from the rectangular frame, and its other end is fixedly connected to the inner wall of the sliding frame.

[0008] Preferably, the number of clamping mechanisms is four sets, and the four sets of clamping mechanisms are respectively arranged in a cross array around the sliding frame.

[0009] Preferably, the horizontal adjustment mechanism includes a first motor, a first lead screw, a horizontal movable frame, a second motor, and a second lead screw. The first lead screw is driven by the first motor and rotatably connected inside the rectangular frame. The horizontal movable frame is connected to the outside of the first lead screw via a threaded drive. The second lead screw is driven by the second motor and rotatably connected to the bottom end of the horizontal movable frame. The lead screw slider is connected to the outside of the second lead screw via a threaded drive.

[0010] Preferably, the drilling mechanism includes a scissor-type telescopic frame, a rotating ring, an electric spindle, and a drill bit. The scissor-type telescopic frame is disposed on the upper surface of the hanger, and the rotating ring is rotatably connected to the intersection point in the middle. The drill bit is connected to the output end of the electric spindle via a spline, and the electric spindle is fixedly installed on the upper surface of the rotating ring. The drill bit passes through the interior of the rotating ring and the hanger, and its bottom end is disposed on the lower surface of the hanger.

[0011] Preferably, there are several rotating rings, and these rotating rings are rotatably connected to the intersection of the middle part of the scissor telescopic frame, and an electric spindle is fixedly installed on the upper surface of each rotating ring.

[0013] The beneficial effects of the above technical solution are as follows:

[0014] This high-precision drilling device for radiator fin processing can adjust the spacing between the drill bits within the drilling mechanism through a spacing adjustment mechanism, thereby achieving synchronous and continuous adjustment of the spacing between all drill bits. This allows the equipment to cover the processing of radiator fins with various hole spacing requirements. Furthermore, the spacing between multiple holes is adjusted equidistantly by a scissor-type telescopic frame within the drilling mechanism, fundamentally eliminating the cumulative error caused by multiple movements of the worktable and ensuring extremely high hole spacing consistency accuracy. A horizontal adjustment mechanism allows the drilling mechanism to move horizontally, and an electric lifting rod drives the drilling mechanism downwards to drill holes in the radiator fins below, enabling the processing of multiple holes at once, greatly improving drilling efficiency. The adsorption base mechanism uses vacuum adsorption force to uniformly adsorb the radiator fin as a whole, avoiding localized concentrated pressure. The clamping mechanism arranged around the perimeter applies a flexible lateral limiting force to the radiator fin from the side, combining with vacuum adsorption to form a stable three-dimensional constraint, effectively suppressing vibration and bending deformation of the thin-walled radiator fins during drilling, ensuring drilling quality.

[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 8 The embodiments are described in detail below.

[0025] This embodiment provides a high-precision drilling device for processing heat sink fins, as shown in the attached figure. Figure 1 As shown, it includes a base 1 and a support frame 2. The upper surface of the base 1 is fixedly connected to an adsorption base mechanism 3 that can adsorb heat sink fins. Specifically, see attached... Figure 2 As shown, the adsorption base mechanism 3 of this utility model includes a grid base 301 with a negative pressure chamber, a negative pressure groove 302, and adsorption holes 303. The grid base 301 is fixedly connected to the upper surface of the base 1, and the negative pressure groove 302 is opened in the middle of its upper surface. Multiple adsorption holes 303 are opened in the inner bottom wall of the negative pressure groove 302, and all multiple adsorption holes 303 communicate with the negative pressure chamber in the grid base 301. A negative pressure connecting pipe communicating with the negative pressure chamber is fixedly connected to the middle of the side of the grid base 301. The negative pressure connecting pipe can communicate with an external negative pressure device, such as... Empty pumps, etc.; The operator can place the heat sink to be processed in the middle of the upper surface of the grid base 301 with its bottom surface in contact with the negative pressure groove 302. By connecting the negative pressure pipe through the external negative pressure equipment, negative pressure is generated in the multiple adsorption holes 303, so that the entire negative pressure groove 302 can tightly adsorb the heat sink, so as to quickly fix the heat sink and ensure that the heat sink is supported without deformation over a large area. Its uniformly distributed adsorption force can effectively overcome the bending deformation of the heat sink caused by uneven mechanical clamping force, and provide a flat reference for high-precision drilling.

[0026] The support frame 2 is fixedly connected to the upper surface of the base 1, and a sliding frame 4 is fixedly connected to the top of the support frame 2. The sliding frame 4 is equipped with a clamping mechanism 5 that can clamp and limit the heat sink fins. Specifically, see attached... Figure 3As shown, the clamping mechanism 5 of this utility model includes a sliding block 501, a compression spring 502 and a clamping plate 503. The clamping plate 503 is vertically fixed to the lower surface of the sliding block 501 and the sliding block 501 is horizontally slidably connected to the inside of the sliding frame 4. The compression spring 502 is horizontally fixed to the side of the sliding block 501 away from the rectangular frame 6 and the other end is fixed to the inner wall of the sliding frame 4. The compression spring 502 has an elastic force on the sliding block 501.

[0027] In one optional embodiment, the number of clamping mechanisms 5 is four sets, and the four sets of clamping mechanisms 5 are respectively arranged in a cross array around the sliding frame 4. When placing the heat sink, the clamping plates 503 around the perimeter can be slid away from each other first. After placing the heat sink on the negative pressure groove 302 on the grid base 301, the clamping plates 503 around the perimeter are released. The sliding blocks 501 will then move closer to each other under the elastic force of the compression spring 502, thereby clamping around the heat sink. Working together with the adsorption base mechanism 3, it can fix and limit the heat sink in three dimensions, ensuring that the heat sink can be firmly fixed and preventing vibration during drilling from affecting the drilling accuracy.

[0028] In one optional embodiment, the number of compression springs 502 on the side of each sliding block 501 can be two. Both compression springs 502 are horizontally built into the corresponding sliding frame 4, which can provide a more stable elastic force to the sliding block 501.

[0029] A rectangular frame 6 is fixedly connected to the middle of the sliding frame 4, and a horizontal adjustment mechanism 7 is provided inside the rectangular frame 6. A lead screw and slider 8 are driven to the movable end of the bottom of the horizontal adjustment mechanism 7; for details, see attached. Figure 4 and 8 As shown, the horizontal adjustment mechanism 7 of this utility model includes a first motor 701, a first lead screw 702, a horizontal movable frame 703, a second motor 704, and a second lead screw 705. The first lead screw 702 is driven by the first motor 701 and rotatably connected inside the rectangular frame 6. The first motor 701 is fixedly installed at one end of the outer side of the rectangular frame 6 and can drive the first lead screw 702 to rotate inside the rectangular frame 6. The horizontal movable frame 703 is connected to the outside of the first lead screw 702 through a threaded transmission. The second lead screw 705 is driven by the second motor 704 and rotatably connected to the bottom end of the horizontal movable frame 703. The second motor 704 is fixedly installed on the side of the horizontal movable frame 703. The lead screw slider 8 is connected to the outside of the second lead screw 705 through a threaded transmission. The second motor 704 can drive the second lead screw 705 to rotate, thereby driving the external lead screw slider 8 to move in the direction of the second lead screw 705.

[0030] Furthermore, a first guide rod 13 is fixedly connected to the end of the rectangular frame 6 away from the first lead screw 702. The first guide rod 13 is parallel to the first lead screw 702 and passes through the end of the horizontal movable frame 703 away from the first lead screw 702. It can guide and limit the horizontal movable frame 703, ensuring that the horizontal movable frame 703 can only reciprocate along the axial direction of the first guide rod 13. A second guide rod 14 is also fixedly connected inside the horizontal movable frame 703, which can guide and limit the lead screw slider 8. The second guide rod 14 is horizontally corresponding to the second lead screw 705 and is set above the second lead screw 705. The top end of the lead screw slider 8 is sleeved on the outside of the second guide rod 14 and can slide laterally outside it, so that the second lead screw 705 drives the lead screw slider 8 to reciprocate along the axial direction of the second guide rod 14.

[0031] The first motor 701 drives the horizontal movable frame 703 to move horizontally via the first lead screw 702, and the second motor 704 drives the lead screw slider 8 to move horizontally via the second lead screw 705. The moving direction of the horizontal movable frame 703 is perpendicular to the moving direction of the lead screw slider 8, thereby enabling the drilling mechanism 11 below to move arbitrarily on the horizontal plane. This facilitates the adjustment of the drilling mechanism 11 to correspond with different parts of the radiator fins, which is beneficial for drilling holes in different parts.

[0032] As attached Figure 5 As shown, electric lifting rods 9 are fixedly installed on both sides of the lead screw slider 8. A hanger 10 is fixedly connected to the bottom of the movable end of the electric lifting rod 9, and an adjustable-space drilling mechanism 11 is provided on the upper surface of the hanger 10. The electric lifting rod 9 can drive the drilling mechanism 11 to move up and down, thereby drilling vertical holes in the radiator fins below; specifically, see attached... Figure 6 As shown, the drilling mechanism 11 includes a scissor-type telescopic frame 1101, a rotating ring 1102, an electric spindle 1103, and a drill bit 1104. The scissor-type telescopic frame 1101 is disposed on the upper surface of the hanger 10, and the rotating ring 1102 is rotatably connected to the intersection of the middle part of the frame. The rotating ring 1102 can act as the pivot of the intersection of the scissor-type telescopic frame 1101, ensuring that the scissor-type telescopic frames 1101 are linked together. The drill bit 1104 is connected to the output end of the electric spindle 1103 by a spline, and the electric spindle 1103 is fixedly installed on the upper surface of the rotating ring 1102. The drill bit 1104 passes through the interior of the rotating ring 1102 and the hanger 10, and its bottom end is disposed on the lower surface of the hanger 10. Slide grooves are provided on both sides of the upper surface of the hanger 10. The drill bits 1104 at both ends of the scissor-type telescopic frame 1101 are respectively inserted into the slide grooves on both sides, which can ensure that the drill bits 1104 on both sides can move with the scissor-type telescopic frame 1101 when it is in motion.

[0033] In one alternative implementation, as shown in the appendix Figure 7As shown, there are several rotating rings 1102, and these rotating rings 1102 are rotatably connected to the intersection of the middle part of the scissor telescopic frame 1101. Each rotating ring 1102 has an electric spindle 1103 fixedly installed on its upper surface. The rotating ring 1102 in the middle of the scissor telescopic frame 1101, the electric spindle 1103 and the drill bit 1104 installed above it are always in the middle of the hanger 10 and remain in a constant horizontal position. Only the rotating rings 1102 on both sides will change position, thereby adjusting the distance between two adjacent drill bits 1104. The distance between each drill bit 1104 is always the same, which is convenient for drilling multiple equidistant holes at the same time. Different hole spacings can be adjusted according to the processing requirements of the radiator fins.

[0034] One side of the upper surface of the hanger 10 is provided with an adjustable spacing mechanism 12 for the drilling mechanism 11, as detailed in the attached diagram. Figure 6 As shown, the spacing adjustment mechanism 12 of this utility model includes a third motor 1201, a third lead screw 1202, and a lead screw sleeve 1203. The third lead screw 1202 is connected to the output end of the third motor 1201 via a spline and is horizontally rotatably connected above the hanger 10. A support plate for supporting the third lead screw 1202 is fixedly connected to the upper surface of the hanger 10, which can support the third lead screw 1202 in a horizontal state. The lead screw sleeve 1203 is fixedly connected to the rotating ring 110 of the scissor-type telescopic frame 1101 near the spacing adjustment mechanism 12. The third motor 1201 is fixedly installed in the middle of the hanger 10. The third motor 1201 drives the third screw 1202 to rotate, which can drive the screw sleeve 1203 to move horizontally back and forth, thereby driving the rotating ring 1102 on this side to move horizontally, and through the scissor telescopic frame 1101, it drives the rotating ring 1102 on the other side to move synchronously in the opposite direction, thereby adjusting the spacing of each rotating ring 1102 and achieving the purpose of adjusting the spacing of the drill bit 1104.

[0035] To enable the horizontal movement of the rotating ring 1102, a third guide rod 15 is fixedly connected to the upper surface of the hanger 10. The third guide rod 15 is horizontally fixedly connected to the upper surface of the hanger 10 and is set parallel to the third lead screw 1202. A sleeve 16 is also fixedly connected to the side of the rotating ring 1102 that is away from the lead screw sleeve 1203. The sleeve 16 is sleeved on the outside of the third guide rod 15. The third guide rod 15 can limit the movement of the rotating ring 1102 through the sleeve 16, so that it can only move horizontally back and forth along the axial direction of the third guide rod 15, thereby ensuring that the drill bits 1104 on both sides of the scissor telescopic frame 1101 can always move horizontally in a vertical state, ensuring the smooth adjustment of the drill bits 1104.

[0036] The first motor 701, the second motor 704, the electric lifting rod 9, the electric spindle 1103, and the third motor 1201 are all electrically connected to the external control unit and are all electrically connected to the external circuit through wires.

[0037] In summary, the high-precision drilling device for processing the radiator fins follows these steps:

[0038] 1. Adjust the spacing of drill bits 1104 according to the required hole spacing, turn on the third motor 1201, drive the third lead screw 1202 to rotate, drive the lead screw sleeve 1203 connected to it to move horizontally, and the lead screw sleeve 1203 drives a rotating ring 1102 at one end of the scissor telescopic frame 1101 to move. Through the linkage of the scissor telescopic frame 1101, the spacing between all rotating rings 1102 changes synchronously, thereby adjusting all drill bits 1104 to achieve the preset hole spacing.

[0039] 2. Slide the sliding blocks 501 around the perimeter outwards to move the clamping plate 503 away from the center of the device, leaving enough space for placement. Place the heat sink to be processed stably on the grid base 301, so that its bottom surface is in contact with the negative pressure groove 302 area. Then slowly release the sliding blocks 501 around the perimeter. The elastic force of the compression spring 502 will push the clamping plate 503 to flexibly contact and clamp the side wall of the heat sink from all sides, completing the initial lateral limit.

[0040] 3. Activate the external negative pressure device. The negative pressure is transmitted to the internal negative pressure chamber through the negative pressure pipe on the side of the grid base 301. The suction force is generated through the adsorption hole 303, which firmly and evenly adsorbs the heat sink fins onto the surface of the grid base 301.

[0041] 4. Turn on the first motor 701 to drive the first lead screw 702 to rotate, which in turn drives the horizontal movable frame 703 to move along the direction of the first guide rod 13; and drive the second lead screw 705 to rotate through the second motor 704, which in turn drives the lead screw slider 8 to move along the direction of the second guide rod 14, which drives the entire drilling mechanism 11 suspended below the hanger 10 to move in the horizontal plane, so that the tips of all drill bits 1104 are precisely aligned with the predetermined drilling positions on the radiator fins;

[0042] 5. Start all electric spindles 1103, drive drill bit 1104 to rotate at high speed, and control the moving end of electric lifting rod 9 to extend synchronously, pushing the hanger 10 and the entire drilling mechanism 11 to descend smoothly. The high-speed rotating drill bit 1104 then contacts and drills into the radiator fins; electric lifting rod 9 feeds according to the preset drilling depth, drilling all mounting holes at once.

[0043] 6. After drilling is completed, control the electric lifting rod 9 to retract synchronously, drive the drill bit 1104 out of the radiator surface, and then turn off the electric spindle 1103 to complete the drilling of the radiator.

[0044] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
